ASTM(American Society for Testing & Materials)

LECO has been involved with ASTM International for over 30 years, with employees serving on committees ranging from cement, to nuclear fuel cycle, to additive manufacturing technologies, to mechanical testing , and more. As with our instruments, we work with ASTM to both push our analytical abilities forward with new methods and rework old methods to keep them up to date with current and cutting-edge technology.
